Question

Do Uranus and Neptune have a hotter core than Jupiter and Saturn?

Answer 1

Jupiter and Saturn have significant internal heat sources, indicating hotter cores compared to Uranus, which emits no internal heat, and Neptune, which has only a small internal heat source.

Step-by-step explanation:

The question asks whether Uranus and Neptune have hotter cores than Jupiter and Saturn. While the core compositions are similar across these giant planets, consisting of rock and ice, Uranus and Neptune are much smaller and have higher densities. However, in terms of internal heat, Jupiter and Saturn have significant internal heat sources, while Uranus does not emit a measurable amount of internal heat, and Neptune has only a small internal heat source. This suggests that Jupiter and Saturn have hotter cores than Uranus and Neptune.
